The last one has a work area to the left. The blue warp core is above the work area (actually the outside casing, since the warp core itself is contained inside, for protection and easier ejection). The vertical bright blue column to the right is the Dilithinum Chamber.

As for the angle, No idea which way the camera is facing in relation to the ship I just created an Engine Control room. The room in the back is just some work stations, systems and other access to other parts of the Engineering department
